u have to buy echanted filement the only thing u can find in that quest is battle core and
scrap metal. but battle cores are rare thats why u might not be finding em

Once you collect 10 pcs of scrap metal, then u go and again fight the doom cola or drill
(here I'm not sure if u wud have to press the button outside the house - I did), u will
get the drive unit (atleast I got it.). But tell u what the pet that he made from the
drive unit and scrap metal was not gr8. It gave 4-12 metal (the dragon is much better).
But there is one good thing about the pet he made, I could sell it off for 1000 Gold. Try
your luck.

hi i have been doing this quest for a long time and all it ever gives me is scrap metal.
Even when i get 10 and i push the button nothing happensc got any ideas?

you get a battle core by doing the quest usually 15 times and you need any armor or wep
that gives you bonus/luck
